Description

接入点切换方法、装置及设备 技术领域
本发明涉及无线通信技术领域，特别涉及一种接入点切换方法、装置及设备。
背景技术
随着移动智能终端普及，用户日益增加的移动数据业务给运营商的蜂窝网络造成严峻的流量压力。特别是在商场、写字楼、体育馆、机场、会展、交通枢纽等人流量较大的场合，网络容量已经远远不能满足用户需求。为了解决上述问题，时下提出了一种将蜂窝网络和WiFi(Wireless Fidelity，无线保真)网络进行融合的方案，即同时提供蜂窝网络和WiFi网络等多制式的接入方式。实现蜂窝网辅助WiFi发现与选择，用户能够无感知地接入WiFi网络，通过WiFi网络承载数据业务，以此来缓解蜂窝网络的流量压力。而对于一个用户设备来说常常会处于移动状态下，在移动状态下时，为了保证通信质量，需要用户设备在部署的各个AP(Access Point，接入点)之间进行切换。
现有技术中，用户设备在移动状态下采取图1所示的方式进行AP切换。其中，eNB指代演进型Node B，为LTE(Long Term Evolution，长期演进)中基站的名称。在eNB与WT(WLAN Termination，WLAN终结单元)完成接口建立和可用BSSID(Basic Service Set Identifier，基础服务集标识)更新设置后，向用户设备发送WiFi网络邻区测量指示，以触发用户设备对WiFi网络邻区进行信号测量。整个测量过程通常需要耗时1至5秒。之后，用户设备将满足策略事件的测量结果上报至eNB。其中，策略事件用于过滤不满足上报条件的测量结果，比如信号强度小于一定阈值。eNB根据上报的测量结果生成一个可用AP列表，并将可用AP列表下发至用户设备。用户设备在可用AP列表中选择一个AP接入。在用户设备处于移动状态下时，用户设备自行控制是否在可用AP列表包含的各个AP之间进行切换。
在实现本发明的过程中，发明人发现现有技术至少存在以下问题：
上述AP切换方式需要用户设备进行WiFi网络的邻区测量，不但浪费了 WiFi空口资源，而且延迟了用户设备接入WiFi网络的时间；此外，由于用户设备自行控制是否进行AP切换，因此针对那些对AP切换表现迟钝的用户设备来说，会出现有信号质量更好的AP可以接入，但是用户设备依然与源AP保持连接的情况，即便源AP的信号质量已经很差，因此采用上述AP切换方式用户设备无法在短时间内快速接入最优AP，降低了整个网络的性能。
发明内容
为了解决上述技术问题，本发明实施例提供了一种接入点切换方法、装置及设备。所述技术方案如下：
本发明实施例提供了一种接入点切换方法，适用的场景为接入点与蜂窝小基站共盒(Box)部署或共站部署，该接入点切换过程既可由源基站控制执行，也可由目标基站控制执行，所述方法包括：
判断用户设备是否从源基站切换至目标基站；若用户设备从源基站切换至目标基站，则获取目标基站与目标接入点之间的对应关系；根据该对应关系，确定目标接入点的标识信息；之后，根据该标识信息生成接入命令，并向所述用户设备下发该接入命令，由所述用户设备在接收到该接入命令后，根据该接入命令，由源接入点切换至目标接入点。
在本发明实施例中，对于源基站和目标基站来说，二者指示切换接入点过程中唯一的不同之处在于：获取目标基站与目标接入点之间的对应关系的方式不同。需要说明的是，本发明实施例中每一个蜂窝小基站都会收集与其共站部署或共盒部署的接入点的标识信息，并根据自身的标识信息和接入点的标识信息，建立一个基站与接入点之间的对应关系。也即，每一个蜂窝小基站仅会收集与自身相关的接入点的信息。同时，每一个蜂窝小基站还可以将自身存储的与接入点之间的对应关系上报至接入点控制器，由接入点控制器对全部蜂窝小基站的上述对应关系进行存储。
因此，当上述接入点切换方法由源基站执行时，源基站需要从接入点控制器获取目标基站与目标接入点之间的对应关系，而当上述接入点切换方法由目标基站执行时，目标基站可以直接从自身的存储介质中获取上述对应关系。也即，对于每一个蜂窝小基站来说，根据与接入点位置的绑定关系自动生成与接入点之间的对应关系。其中，源接入点指代用户设备在发生基站切换之前接入的接入点，目标接入点指代用户设备在发生基站切换之后应接入的接入点。
以目标基站执行上述接入点切换方法为例，则上述获取所述目标基站与目标接入点之间的对应关系之前，所述方法还包括：
所述目标基站获取与其共站部署的所述目标接入点的标识信息；所述目标基站根据自身的标识信息和所述目标接入点的标识信息，建立所述目标基站与所述目标接入点之间的对应关系；所述目标基站存储所述对应关系。
如果目标基站与目标接入点是采用共盒部署的，则上述获取所述目标基站与目标接入点之间的对应关系之前，所述方法还包括：
所述目标基站获取与其共盒部署的所述目标接入点的标识信息；所述目标基站根据自身的标识信息和所述目标接入点的标识信息，建立所述目标基站与所述目标接入点之间的对应关系；所述目标基站存储所述对应关系。
此外，在判断用户设备是否由源基站切换至目标基站时，根据蜂窝小基站类型的不同采取的判断方式也不同。
针对Pico基站来说，判断方式为：若判断出所述用户设备发生小区切换，则确定所述用户设备由源基站切换至目标基站，将目标小区对应的基站确定为所述用户设备切换的目标基站。
针对Lampsite基站，判断方式为：对所述用户设备的当前所在位置进行定位，得到定位信息；若判断出所述定位信息与所述用户设备接入的源基站的位置信息不匹配，则确定所述用户设备由源基站切换至目标基站，将与所述定位信息匹配的基站确定为所述用户设备切换的目标基站。
本发明实施例提供的技术方案的有益效果是：
在获取到目标基站与目标接入点之间的对应关系后，利用该对应关系可在用户设备由源基站切换至目标基站时，同步完成由源接入点至目标接入点的切换，不但无需用户设备对WiFi网络进行邻区测量，而且直接由基站下发最优接入点的接入命令，这样无论用户设备对接入点切换表现迟钝与否，用户设备在接收到该接入命令后，均立即切换到最优接入点覆盖的WiFi网络下，节约了WiFi空口资源，且大大降低了用户设备接入WiFi网络的时间，提高了WiFi网络的吞吐率，提升了整个网络的性能。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
在对本发明实施例进行详细地解释说明之前，先对本发明实施例涉及的场景和系统架构进行叙述。参见图2，本发明实施例涉及的接入点切换方法适用的场景为AP与蜂窝小基站共盒部署或共站部署。如图2所示，其分别示出了AP与Pico(微微)基站共盒部署的场景、AP与Pico基站共站部署的场景、AP与Lampsite基站共盒部署的场景。在图2中，共盒部署指代将AP与基站集成在一起，比如二者集成在一个Box中。针对共盒部署的场景，AP或者集成在Pico基站中，或者集成在Lampsite基站中。针对共站部署的场景，AP与基站没有集成与一体，而是相互独立，二者之间相互连接。
在蜂窝网络与WiFi网络融合后，实现通过蜂窝网辅助WiFi发现与选择。为了实现用户设备移动过程中，在由源基站切换至目标基站的同时，同步完成WiFi小区的切换，本发明实施例提出了将共站部署或共盒部署的蜂窝小基站与AP进行绑定，建立一种蜂窝小基站与AP之间的对应关系，根据蜂窝小基站与AP之间的对应关系为用户设备选择最优切换AP的方式。参见图3，当用户设备从蜂窝网络下的基站1(Pico基站1或Lampsite基站1)所在的位置1移动到基站2(Pico基站2或Lampsite基站2)所在的位置2时，根据基站与AP之间的对应关系，可以判断出用户设备对应的最优AP从AP1变更为AP2。因此，当用户设备切换蜂窝小基站(由基站1切换为基站2)的同时，还会通过 Mobility Set命令向用户设备下发AP2的标识信息，驱动用户设备同步完成AP切换，使得用户设备从AP1覆盖的WiFi小区切换至AP2覆盖的WiFi小区。在本发明实施例中，蜂窝小基站实质指代Pico网元或者pRRU(Pico Remote Radio Unit，微微射频拉远单元)。
图4是本发明实施例提供的一种基站eNB的结构示意图。参见图4，发射机401、接收机402、存储器403和处理器404，存储器403、发射机401和接收机402分别与处理器404连接，存储器403存储有程序代码，处理器404用于调用程序代码，执行以下操作：
若用户设备从源基站切换至目标基站，则获取所述目标基站与目标接入点之间的对应关系；根据所述对应关系，确定与所述目标基站匹配的所述目标接入点的标识信息；根据所述标识信息生成接入命令；通过发射机401向所述用户设备发送所述接入命令，所述接入命令用于指示所述用户设备由源接入点切换至所述目标接入点。
在另一个实施例中，处理器404用于调用程序代码，执行以下操作：
获取与其共站部署的所述目标接入点的标识信息；根据自身的标识信息和所述目标接入点的标识信息，建立所述目标基站与所述目标接入点之间的对应关系；存储所述对应关系；或，
获取与其共盒部署的所述目标接入点的标识信息；根据自身的标识信息和所述目标接入点的标识信息，建立所述目标基站与所述目标接入点之间的对应关系；存储所述对应关系；
所述目标基站获取自身存储的与所述目标接入点之间的所述对应关系。
需要说明的是，本步骤适用于目标基站执行接入点切换方法的情形。
在另一个实施例中，处理器404用于调用程序代码，执行以下操作：
从接入点控制器获取所述目标基站与目标接入点之间的对应关系，所述对应关系由所述接入点控制器从所述目标基站获取得到。
需要说明的是，本步骤适用于源基站执行接入点切换方法的情形。
在另一个实施例中，处理器404用于调用程序代码，执行以下操作：
若判断出所述用户设备进行了小区切换，则确定所述用户设备从所述源基站切换至所述目标基站，将目标小区对应的基站确定为所述目标基站。
在另一个实施例中，处理器404用于调用程序代码，执行以下操作：
对所述用户设备的当前所在位置进行定位，得到定位信息；
若判断出所述定位信息与所述源基站的位置信息不匹配，则确定所述用户设备从所述源基站切换至所述目标基站，将与所述定位信息匹配的基站确定为所述目标基站。
本发明实施例提供的基站，在获取到目标基站与目标接入点之间的对应关系后，利用该对应关系可在用户设备由源基站切换至目标基站时，同步完成由源接入点至目标接入点的切换，不但无需用户设备对WiFi网络进行邻区测量，而且直接由基站下发最优接入点的接入命令，这样无论用户设备对接入点切换表现迟钝与否，用户设备在接收到该接入命令后，均立即切换到最优接入点覆盖的WiFi网络下，节约了WiFi空口资源，且大大降低了用户设备接入WiFi网络的时间，提高了WiFi网络的吞吐率，提升了整个网络的性能。
图5A是本发明实施例提供的一种接入点切换方法的流程图。交互主体为用户设备、源eNB和AP。参见图5A，本发明实施例提供的方法流程包括：
501a、源eNB建立与AP之间的对应关系，并对该对应关系进行存储。
在本发明实施例中，网络融合具体指代LTE网络与WLAN(Wireless Local AreaNetworks，无线局域网络)融合。此处的源eNB指代Pico网元或者pRRU。源eNB在与WT建立Xw-C接口连接后，会获取LWA(LTE/WLAN Aggregation，长期演进技术与无线局域网聚合)网络下与其共站部署或者共盒部署的AP的标识信息，并建立与该AP之间的对应关系。也即，本发明实施例所述的AP指代与源eNB共站部署或共盒部署的AP。
其中，标识信息可为ESN(Electronic Serial Number，电子序列号)、MAC(MediaAccess Control，介质访问控制)地址、SN(Serial Number，产品序列号)等，本发明实施例对此不进行具体限定。上述每一种标识信息均可对一个设备进行唯一标识。需要说明的是，对于一个蜂窝小基站来说，其通常仅会建立并存储与其共站部署或者共盒部署的AP之间的对应关系。比如一个Pico网元1和一个AP1共站部署，则在Pico网元1中仅会存储与AP1之间的对应关系。其中，源eNB与AP之间的对应关系生成过程如下：
第一种情况针对源eNB与AP共站部署的场景。
获取与其共站部署的接入点的标识信息；根据自身的标识信息和该接入点的标识信息，建立源eNB与该接入点之间的对应关系，并存储该对应关系。
第二种情况针对源eNB与AP共盒部署的场景。
获取与其共盒部署的接入点的标识信息；根据自身的标识信息和该接入点的标识信息，建立源eNB与该接入点之间的对应关系，并存储该对应关系。
在建立蜂窝小基站与AP之间的一一位置绑定关系后，通过蜂窝小基站便可查询到对应的AP，实现通过锁定蜂窝小基站的位置便可锁定AP的位置。
502a、源eNB判断用户设备是否切换至目标基站；若用户设备切换至目标基站，则从接入点控制器获取目标基站与目标AP之间的对应关系，根据该对应关系确定与目标基站对应的目标AP。
由于用户设备是可移动的，因此当用户设备处于移动状态下时，为保证通信质量用户设备还需在不同的蜂窝基站之间进行切换，也即可能需要不同的蜂窝基站为用户设备提供通信服务。在本发明实施例中，基于基站的类型不同，采取不同的方式对用户设备是否发生基站切换进行判断，详细如下：
第一种方式、针对基站类型为Pico基站的情形。
源eNB判断用户设备是否发生小区切换；若用户设备发生小区切换，则确定用户设备切换至目标eNB，将目标小区对应的基站确定为用户设备切换的目标基站。
对于Pico基站来讲，由于一个Pico基站对应一个蜂窝小区，因此用户设备发生了蜂窝小区切换，即表征用户设备发生了Pico基站切换，也即为用户设备提供通信服务器的基站位置发生变化。在判断用户设备是否发生小区切换时，可通过检测用户设备接入的蜂窝小区的小区号是否发生变更的方式，本发明实施例对此不进行具体限定。
第二种方式、针对基站类型为Lampsite基站的情形。
源eNB对用户设备的当前所在位置进行定位，得到定位信息；判断该定位信息与自身的位置信息是否匹配；若该定位信息与自身的位置信息不匹配，则确定用户设备切换至目标eNB，将与该定位信息匹配的基站确定为用户设备切换的目标eNB。
对于Lampsite基站来讲，由于一个蜂窝小区既可对应一个Lampsite基站，也可对应几个Lampsite基站，因此采取对用户设备进行位置定位的方式判断是否发生基站切换，即是否在pRRU之间发生了切换。
在本发明实施例中，源eNB在对用户设备进行定位时，可采取小区号定位方式、基于电波传播时间/电波传播时间差的定位方式、基于电波入射角的定 位方式、基于接收信号强度的定位方式、基于A-GPS(Global Positioning System，全球定位系统)的定位方式中的任一种实现，本发明实施例对此不进行具体限定。需要说明的是，接入点控制器会收集各个蜂窝小基站存储的上述对应关系，或者各个蜂窝小基站会向接入点控制器上报自身存储的对应关系，因此接入点控制器维护有各个蜂窝小基站存储的上述对应关系。所以，源eNB在检测到用户设备切换至目标基站后，会从接入点控制器获取目标基站与目标AP之间的对应关系，并根据该对应关系确定与目标基站对应的目标AP。
503a、源eNB向用户设备下发目标AP的接入命令。
在本发明实施例中，接入命令具体可为Mobility Set命令。其中，Mobility Set命令为LWA的命令提示符cmd。该接入命令中可包括目标AP对应WiFi小区的小区号。对于一个AP来说，在组网时均为每一个AP建立了标识信息与小区号之间的对应关系。在确定目标AP后，根据上述对应关系即可确定与目标AP匹配的小区号。其中，小区号具体可为BSSID，还可为SSID(Service Set Identifier，服务集标识)，本发明实施例对此不进行具体限定。优选地，采用BSSID，因为BSSID可以标识物理地址。
504a、用户设备根据该接入命令，由源AP切换至目标AP。
用户设备在接收到源eNB发送的接入命令后，根据该接入命令中包含的小区号便可完成由源AP至目标AP的切换。实现了进行蜂窝小基站切换的同时，同步完成最优AP的切换。与现有技术不同的是，源eNB不向用户设备下发一个可用AP列表，而是仅下发一个最优AP的相关信息，即源eNB指定了用户设备应切换的AP，这样用户设备在接收到接入命令后，即刻进行最优AP切换，实现驱动用户设备进行AP切换。因此即便用户设备对切换表现出极端的迟钝也无妨，不会出现有信号更好的AP可以接入的情况下，用户设备还与原来接入的AP保持连接，极大地提升了用户体验和网络性能。
本发明实施例提供的方法，在获取到目标基站与目标接入点之间的对应关系后，利用该对应关系可在用户设备由源基站切换至目标基站时，同步完成由源接入点至目标接入点的切换，不但无需用户设备对WiFi网络进行邻区测量，而且直接由基站下发最优接入点的接入命令，这样无论用户设备对接入点切换表现迟钝与否，用户设备在接收到该接入命令后，均立即切换到最优接入点覆盖的WiFi网络下，节约了WiFi空口资源，且大大降低了用户设备接入WiFi网络的时间，提高了WiFi网络的吞吐率，提升了整个网络的性能。
图5B是本发明实施例提供的一种接入点切换方法的流程图。交互主体为用户设备、目标eNB和AP。参见图5B，本发明实施例提供的方法流程包括：
501b、目标eNB建立与AP之间的对应关系，并对该对应关系进行存储。
该步骤与上述步骤501a类似，此处不再赘述。无论是源eNB还是目标eNB，均会建立与其共盒部署或者共站部署的AP之间的对应关系。也即，本发明实施例提及的AP指代与目标eNB共盒部署或者共站部署的AP。
502b、目标eNB判断用户设备是否由源eNB切换至自身；若用户设备由源eNB切换至自身，则目标eNB获取自身存储的与AP之间的对应关系，根据该对应关系确定目标AP。
该步骤与上述步骤502a类似，此处不再赘述。由于与AP之间的对应关系存储在自身存储介质中，因此可直接根据该对应关系确定出目标AP。
503b、目标eNB向用户设备下发目标AP的接入命令。
该步骤与上述步骤503a类似，此处不再赘述。
504b、用户设备根据该接入命令，由源AP切换至目标AP。
该步骤与上述步骤504a类似，此处不再赘述。
本发明实施例提供的方法，在获取到目标基站与目标接入点之间的对应关系后，利用该对应关系可在用户设备由源基站切换至目标基站时，同步完成由源接入点至目标接入点的切换，不但无需用户设备对WiFi网络进行邻区测量，而且直接由基站下发最优接入点的接入命令，这样无论用户设备对接入点切换表现迟钝与否，用户设备在接收到该接入命令后，均立即切换到最优接入点覆盖的WiFi网络下，节约了WiFi空口资源，且大大降低了用户设备接入WiFi网络的时间，提高了WiFi网络的吞吐率，提升了整个网络的性能。
